Audi RS6, RS7 & RS Q8 (C8) 4.0 TFSI Performance Ignition Coils - Mantis MTP-1003

Built for Audi Sport's 4.0 TFSI twin-turbo V8 (EA825) in the C8 RS6 Avant, RS7 Sportback and RS Q8, this Mantis high-output ignition coil is the direct upgrade for some of the most heavily tuned fast Audis on the road — cars where a simple Stage 1 map pushes well past 750PS and eight factory coils are left carrying far more load than they were ever specified for.

Why Choose the Mantis MTP-1003?

• 12% More Spark Energy — a neodymium magnetic core stores more energy than the standard ferrite OE coil, for a stronger, more consistent spark across all eight cylinders.
• Built for Boost — the thermal headroom to keep the 4.0 V8 firing cleanly at full boost, from the 600PS originals to the 630–640PS Performance models and well beyond.
• Better Heat Handling — sheds heat more effectively inside the hot-V layout, helping to prevent the misfires that creep in as coils heat-soak.
• Direct OE Plug & Play — same fit, connector and wiring as the factory VAG coil. No coding, VCDS or OBDeleven work needed.
• 2-Year Warranty, UK Stock — UK-engineered with every unit tested, same-day dispatch on orders before 3pm.

Seeing P0301–P0308 misfire codes, a rough cold idle or a flat feel above 4,500rpm? Swap in a full set of eight Mantis MTP-1003 coils — mixed-age coils cause uneven spark and the ECU pulls timing to compensate. Fitting takes around 30–45 minutes.
